CryptoStudio is a premium, privacy-first web application designed for seamless string conversion, encoding, and industrial-grade encryption—all handled entirely within your browser.
Quickly transform data between popular formats:
- Binary & Hexadecimal: Standard low-level data representations.
- Base64, Base32, Base58: Industry-standard text encodings (including Bitcoin-style Base58).
- URI Component: Web-safe URL encoding.
Secure your sensitive information with multiple algorithms:
- AES (Advanced Encryption Standard): The gold standard for modern encryption.
- Rabbit: Specialized cipher for stream encryption.
⚠️ Legacy/Insecure Ciphers (NOT recommended for sensitive data): TripleDES, RC4, XOR.- 🚀 Enhanced Protection (Vault Mode): Up to 7 levels of PBKDF2 key derivation iterations. Level 7 ("Vault Mode") provides extreme resistance against brute-force attacks by introducing significant computational work.
⚠️ Security Notice: Iteration levels 1-3 provide insufficient protection and should not be used PBKDF2 Iteration Levels:
- Level 1: 1
- Level 2: 10
- Level 3: 100
- Level 4: 1000 (minimum for production)
- Level 5: 10000
- Level 6: 100000
- Level 7: 1000000
Note: OWASP recommends a minimum of 600,000 iterations for PBKDF2-HMAC-SHA256 as of 2023. for sensitive data. Always use level 4 or higher for production use.
Full suite of OpenPGP tools powered by openpgp.js:
- Encrypt & Decrypt: Secure message exchange using public/private key pairs.
- Sign & Verify: Ensure message integrity and sender authenticity.
- Key Generation: Dedicated generator for RSA (2048/4096) and ECC (Curve25519) keys.
- Responsive Interface: High-iteration cryptographic tasks are offloaded to Web Workers, keeping the UI responsive.
- Security First: All operations are performed locally. No data ever leaves your machine or is sent to a server.
- Modern Aesthetics: A sleek, dark-themed UI built with TailwindCSS and refined with Inter and JetBrains Mono typography.
- Secure Key Bundling: Download your generated PGP keys in a password-protected (ZipCrypto) ZIP archive.
Simply open index.html in any modern web browser to begin. No installation or account is required.
